1964js is the first N64 emulator written in JavaScript (CoffeeScript to JS). It is (kind of) a port of our N64 emulator for Windows called 1964. 1964 was written in C and C++ for Windows. You can still grab that here.

This project is still in the early stages. The initial goal of this project was to see how well Google Chrome's V8 JavaScript compiler performs.

Instead of building a traditional dynarec (JIT compiler) as we did for 1964 for Windows which translated MIPS directly to x86, 1964js dynamically writes JavaScript to the web page by reversing MIPS code to JavaScript. This JavaScript represents blocks of rom code. Then, if using Chrome for instance, Google's V8 compiler compiles the JavaScript to native code for us automatically.

We've released the source to 1964 1.1. (1964 1.0 was an experimental compiler which breaks games like Perfect Dark and Banjo Tooie. Please use version 1.1) We also did this to support the efforts of the Surreal64 team. Please bear in mind that most of the source has not been touched in over five years.

Improvements:

Kirby's face doesn't stay smashed in with block-linking set to on in Kirby64 - The Crystal Shards.

Loading from a save state would sometimes cause the audio to disappear.

LLE RSP audioplugin(1964audio 2.7). We created a code generator that reverses RSPmicrocodesto C.Thegenerated C source is provided but we are not currently releasing portions of the code generator that creates the C files (namely Gerrit'sDSPopcodesource). Fear not, we provided enough for you to build the project.

Here's your new year's gift. 1964 v0.9.9 is here. With over one year in private development since the release 1964 0.8.5. and with over 3 months in beta testing, 1964 0.9.9 features hundreds of fixes and enhancements. Note: If you have an ATI Radeon video card, download the latest Rice Video plugin from www.emutalk.net, since the older version in the 0.9.9 distribution will have issues for you.
